Our windows have an 'A' energy rating and improve the energy efficiency of your home, as well as saving you money on your heating bills by reducing the amount of energy you use.

Noise reduction

Our uPVC double-glazed windows ensure that you can enjoy peace and quiet in your home at all times. They’ll keep outdoor noise where it belongs – outside.

Weatherproof

Our windows are manufactured from the highest quality materials that stand the test of time against all kinds of weather. They won't rot, rust or warp, no matter what the British climate throws at them!

Customer Reviews

Very pleased with my new windows and doors. They look great! William and George did a brilliant job fitting them. Very clean and tidy workers . A great experience from start to finish. Will recommend this company to others.

Grace Grattan

Emerald recently completed a two day job for us. The quality of the windows & door fitted are first rate. Their communications were very good prior to the work, & they rang ahead on the day they were due to start to confirm what was due to be carried out.

They made the procedure from start to finish a smooth one. We would fully recommend them for future use.

Ian Longdon

We had our windows and doors replaced with Emerald Home Improvements. Absolutely first rate service, they worked all day without stopping and made a first class job. I am very happy with the company and the work. This is a very efficient, well run company and I highly recommend them. I have since ordered guttering and fascias. Thank you to everyone at Emerald and especially to Steve and Scott.
